  Laser cleaning is a new cleaning method. Compared with traditional cleaning, it is more energy-saving, environmental protection, safe and efficient. Laser cleaning is widely used and plays an important role in many fields. Laser cleaning can be used to clean not only organic pollutants, but also inorganic substances, including metal corrosion, metal particles, dust, etc.

  Main methods of laser cleaning:

  1. Laser dry cleaning, that is, using pulse laser direct radiation decontamination;

  2. The method of laser + liquid film is to deposit a layer of liquid film on the surface of the substrate and then decontaminate it with laser radiation;

  3. The method of laser + inert gas is to use inert gas to blow to the surface of the substrate at the same time of laser radiation. When the dirt is peeled off the surface, it will be blown off the surface immediately by the gas to avoid the surface pollution and oxidation again;

  4. After using laser to loosen the dirt, clean it with non corrosive chemical method.

  The first three methods are most commonly used. The fourth method is only found in the cleaning of stone relics.

  Application field of laser cleaning machine:

  1. Metal or glass surface coating removal, rapid paint removal;

  2. Fast rust removal and various oxides;

  3. Remove grease, resin, glue, dust, stain and production residue;

  4. Metal surface roughening and metal surface cleaning in narrow space;

  5. Depainting, derusting, degreasing, oxide and residue treatment before welding or bonding;

  6. Mold cleaning, such as tire mold, electronic mold, food mold;

  7. The oil pollution is removed after the production and processing of precision parts;

  8. Fast cleaning of nuclear power component maintenance;

  9. Oxide treatment, paint removal and rust removal during the production or maintenance of aerospace weapons and ships;

  10. Cultural relics cleaning, rock cleaning, building external surface cleaning.

  Laser cleaning plays an important role in many fields. With the continuous improvement of technology and mass production of equipment, laser cleaning technology will play an important role in cleaning industry. leapion
